This review is a sort of "Memory Upgrade Kit" review, which though useful to the end user without a clue, can pretty much be duplicated by using any price finder engine on mac RAM, like dealram.com, since it only talks about price and the fact that all RAM has a lifetime warranty. Whether or not you can actually execute on that warranty is another matter.
They didn't include the actually specs of the memory that Apple ships with, like ECC, parity, buffering, CL and CAS ratings, chip configurations and speed rating of the chips used on the DIMMs, circuit layers, etc.
That kind of info is often what sets the price of one manufacturer apart from the others.
They also didn't test the RAM other than to use it in a machine, not use a commercial RAM tester to read what it claims it is and check if it is actually in spec or not.
Warranty execution is probably the most useful stat to have, as if it goes bad, some sellers make you seek the manufacturer for warranty and not just let you send it back. Some charge you for shipping after giving you a hard time, etc.
I would love to see a more technical review of the RAM out there that works in Macs.
